Study highlights outdoor activity benefits for preventing myopia in children amidst pandemic challenges

A recent study highlights the impact of outdoor activity on preventing myopia in children, particularly in the context of increased screen time during the pandemic. Children who engaged in online learning with smartphones or tablets were more likely to develop myopia compared to those who used projectors. A pediatric ophthalmologist emphasizes the protective benefits of outdoor time.

The study, presented by BBC, indicated a significant decline in children’s vision in recent years, exacerbated by the pandemic as kids spent more time indoors. In some regions, one in three children is now nearsighted.

While the exact cause of myopia remains unclear, genetic factors contribute, and environmental influences are also significant. The increase in myopia has been notably pronounced in Southeast Asia, with early schooling intensifying cases due to increased near work and reduced outdoor exposure.

Experts warn that while it is believed that spending time on near tasks less than 20 centimeters away promotes myopia, reversing this condition once established is not possible. Researchers are actively looking for ways to prevent the worsening of myopia among affected individuals.

Outdoor activity is touted as a key preventative measure. Continuous recommendations suggest that children should spend at least two hours outside each day. While the impact of outdoor time on existing myopia remains uncertain, it is clear that outdoor exposure is beneficial for eye health.
